Ultrasound biomicroscopy in the diagnosis and management of pars planitis caused by caterpillar hairs.

PURPOSE: To report the use of ultrasound biomicroscopy in the detection of caterpillar hairs in the pars plana in a patient with unilateral pars planitis. METHOD: Ultrasound biomicroscopic imaging of the anterior segment of the eye. RESULTS: Ultrasound biomicroscopy located a hair in the posterior chamber at the first visit and five more in the pars plana 1 month later. This finding was confirmed intraoperatively. CONCLUSION: Ultrasound biomicroscopy is useful in the diagnosis and management of unilateral pars planitis of uncertain cause.

Ultrasound biomicroscopy of sclerotomy sites after pars plana vitrectomy for diabetic vitreous hemorrhage.

OBJECTIVE: This study was aimed at assessing changes at the sclerotomy site using the ultrasound biomicroscope (UBM) in eyes that underwent primary pars plana vitrectomy for complications of proliferative diabetic retinopathy. DESIGN: Prospective, observational case series. PARTICIPANTS: Eighty-six eyes of 84 patients with vitreous hemorrhage caused by proliferative diabetic retinopathy. INTERVENTION: Three-port pars plana vitrectomy followed by UBM evaluation of all sclerotomy sites between 6 and 8 weeks after surgery. Correlation with intraoperative findings done in case of reoperations. Forty-one eyes had repeat UBM at 6 months. MAIN OUTCOME MEASURES: The changes at the sclerotomy site were classified into six groups: well healed, gape, plaque, vitreous incarceration, fibrovascular proliferation, and anterior hyaloidal fibrovascular proliferation (AHFVP). The UBM characteristics of each of the groups were defined. The findings at 6 months were compared with those at 6 to 8 weeks. RESULTS: At 6 to 8 weeks after surgery, most sclerotomies were well healed or had either moderate to high reflective plaques bridging the site. Wound gape was seen in 22.1% of active ports, 32.6% of light ports, and 25.6% of infusion ports. Vitreous incarceration was seen most often at the infusion port (18. 6% of eyes). Fibrovascular proliferation was seen in 9.3% of active ports, 12.8% of light ports, and 15.1% of infusion ports. Thirteen eyes had recurrent vitreous hemorrhage 6 to 8 weeks after surgery. Cases with rebleeding and no fibrovascular proliferation at the sclerotomy on UBM did well with outpatient fluid-air exchange (two eyes) or observation only (three eyes). Those with fibrovascular proliferation on UBM (eight eyes) required more extensive surgery. CONCLUSIONS: UBM is helpful in detecting complications at the sclerotomy sites after pars plana vitrectomy and is an invaluable tool in the assessment of the patient before reoperation.

Ultrasound Biomiscroscopy in the diagnosis and management of cyclodialysis clefts.

PURPOSE: To report the role of Ultrasound Biomicroscopy (UBM) as a tool in the diagnosis and management of cyclodialysis clefts. METHODS: Six eyes of 6 patients with hypotony and suspected or diagnosed cyclodialysis clefts underwent UBM evaluation. Post-treatment UBM was performed in four eyes to assess the effect of the treatment. RESULTS: Cyclodialysis clefts were accurately diagnosed and delineated in 6 eyes by UBM. Complete closure was documented after treatment in 3 eyes, and a residual cleft in one eye. These findings were compared to gonioscopic findings. CONCLUSIONS: UBM is a safe, accurate and noninvasive diagnostic tool in the diagnosis of cyclodialysis clefts and is of particular use when other conventional methods of diagnosis are inconclusive.

Use of the esophageal detector device in a newborn-piglet model.

STUDY OBJECTIVE: To determine the accuracy of the esophageal detector device (EDD) in predicting correct endotracheal tube (ETT) placement in a newborn-piglet model. METHODS: We used an EDD, comprising a 5-, 10- or 20-mL syringe attached to 4-mm tubing fitted to a 15-mm ETT adapter, to aspirate gas from cuffed or uncuffed ETTs placed in the trachea or esophagus of each newborn piglet. During aspiration, we noted any resistance encountered while pulling back the plunger of the syringe and recorded the total volume of gas aspirated into the syringe. A positive test, signifying tracheal ETT placement, was defined as the ability to freely aspirate gas without resistance and the aspiration of enough gas to fill the entire volume of the syringe. A negative test, signifying esophageal ETT placement, was defined as resistance encountered during the aspiration of gas into the syringe and rebound of the syringe plunger, leading to aspiration of a volume of gas less than the total volume of the syringe. RESULTS: We conducted 444 trials (222 for uncuffed ETTs, 222 for cuffed ETTs). ETT size ranged from 3.0 to 4.5 mm. For cuffed ETTs, the 5-mL syringe had a sensitivity of 100% and a specificity of 5%, the 10-mL syringe had a sensitivity of 95% and a specificity of 16%, and the 20-mL syringe had a sensitivity of 86% and a specificity of 97%. For uncuffed ETTs, the 5-mL syringe had a sensitivity of 100% and a specificity of 5%, the 10-mL syringe had a sensitivity of 97% and a specificity of 24%, and the 20-mL syringe had a sensitivity of 81% and a specificity of 100%. CONCLUSION: No syringe had 100% sensitivity and specificity in correctly predicting ETT placement. The 20-mL syringe had the highest combination of sensitivity and specificity. Further studies are warranted to determine whether the EDD using a 20-mL syringe would aid in the prediction of correct ETT placement in the pediatric population.

Subretinal fibrosis and nonrhegmatogenous retinal detachment associated with multifocal central serous chorioretinopathy.

PURPOSE: To report the rare occurrence of subretinal fibrosis in patients with multifocal central serous chorioretinopathy and evaluate the role of systemic corticosteroids and the effects of laser photocoagulation on multifocal leaks. METHODS: A total of 29 patients (mean age, 37.7 years; 89.7% male) treated for subretinal fibrosis and multifocal central serous chorioretinopathy from 1983-1995 were reviewed retrospectively. Mean follow up was 26 months (range, 6.8-81 months). RESULTS: Retinal detachment involved the macula in 72.4% cases. Fluorescein angiography showed a mean of 6.7 (range, 2-22) central serous chorioretinopathy leaks and a mean of 1.8 (range, 1-5) retinal pigment epithelial detachments. The fundus pictures of 23 patients who were taking systemic corticosteroids showed no improvement. Following laser treatment, however, retinal reattachment was obtained in all eyes, and improvement in visual acuity of > 2 Snellen lines was noted in 68.9% of patients. CONCLUSIONS: The presence of subretinal fibrosis with secondary retinal detachment in otherwise healthy young patients, particularly in men, should alert the physician to look for multifocal central serous retinopathy leaks. Systemic corticosteroids did not prove effective in treating these patients, although laser treatment is recommended for each leak identified on an angiogram.

A multivariate analysis of anatomic success of recurrent retinal detachment treated with pneumatic retinopexy.

PURPOSE: The purpose of the study is to determine the success rate of pneumatic retinopexy (PR) after failed scleral buckling and to elucidate the predictors for anatomic failure by multiple logistic regression analysis. METHODS: Thirty-six eyes with recurrent retinal detachment after failed scleral buckling underwent PR. Intraocular tamponade was attained with SF6 (20 eyes), C3F8 (13 eyes), and air (3 eyes). Median follow-up was 14 months. RESULTS: Retinal reattachment was obtained in 69.4%. Multivariate analysis identified two risk factors for failure: location of retinal break either on the posterior slope or posterior to buckle (P = 0.01) and extent of retinal detachment greater than two quadrants (P = 0.02). CONCLUSIONS: Pneumatic retinopexy is an effective alternative to revision surgical operations if the leaking retinal break is located on the buckle.

Vitrectomy for accidental intraocular steroid injection.

BACKGROUND: Accidental perforation of the globe and intraocular injection of steroid is a potential complication of periocular injections. Final outcomes in eyes in which this complication has occurred have been reported to be unsatisfactory in the past. However, the advent of vitrectomy has altered their prognosis significantly. METHODS: A retrospective analysis was done of five cases of accidental intraocular steroid injection, treated by vitrectomy. Additional procedures involved treatment of retinal breaks (where required) with endolaser or transscleral cryopexy. Scleral buckling was done in one case. RESULTS: Barring one case in which retinal detachment developed, there were no postoperative complications. At last follow up all patients had satisfactory recovery of visual acuity; had attached retina; and quiet anterior chamber and vitreous cavities. CONCLUSION: Vitrectomy is associated with satisfactory results in cases of accidental intraocular steroid injection. Delay up to a few days does not seem to materially influence the outcome.
